Fix dirty COW vulnerability in the linux kernel (CVE-2016-5195)
According to the wikipedia:
Dirty COW (Dirty copy-on-write) is a computer security vulnerability for
the Linux kernel that affects all Linux-based operating systems
including Android. It is a local privilege escalation bug that exploits
a race condition in the implementation of the copy-on-write mechanism
discovered by Phil Oester. The bug has been lurking in the Linux kernel
since version 2.6.22 (released in September 2007), and has been actively
exploited at least since October 2016.
